PPT-Work and Power Problems

Use this PowerPoint to learn how to solve work and power problems This is for the handout with only 6 questions Work Work Force multiplied by Distance For work to be done a force must be applied to an object and the object must move in the direction of the force. What do the F and d stand for?. What are the units for F and d?. What do the W and t stand for?. What is the unit for t?. Work is a form of energy. What is the unit for work and energy?.  .

External power which comes from a home or office wall outlet, is the power everyone tends to take for granted; as long as it’s fine.. er 10-12. Power and work and efficiency. Additional Note. In case you did read in your text, which I would prefer if you did you may have missed the following definition…. Mechanical energy: Is the sum of potential and kinetic energy in a system.. In text: Ch 5. Do you already know these words?. Work – . Energy – . Power – . 2.3.1 Outline . what is meant by work.. First a demo:. One volunteer. Hold a couple of books and walk across the room.. Work . = W. The product of the force . F . applied to an object over a distance . d . in which the object travels as a result of the force. Joule . (J) . is the base unit of work. (Force and distance must be parallel to each other). power. incorporates both the concepts of work and time. . Power is work done per unit time.. Average power, P is the average rate at which work . W. is done, and it is obtained by dividing . W. by the time t required to perform the work:. Work. . is done when an object moves through a distance because of a . Force. . acting upon the object.. 2. When calculating work, you should use the formula: work = force X . distance. .. 3. The SI unit for work is the . Work is the product of the force on an object and the distance through which the object is moved: the quantity . force . ×. distance. Work. If the force is constant and the motion takes place in a straight line in the direction of the force, the work done on an object by a net force is the product of the force and the distance through which the object is moved.. Principles of Engineering. Work. . Work. (symbol . W. ) is the energy transferred when a force . F. is applied to an object moving through a . distance . d. .. The SI . unit of work or . energy is the joule (symbol J).. Principles of Engineering. Work. . Work. (symbol . W. ) is the energy transferred when a force . F. is applied to an object moving through a . distance . d. .. The SI . unit of work or . energy is the joule (symbol J).. Energy, Work, & Power SP3. Students will evaluate the forms and transformations of energy. a. Analyze, evaluate, and apply the principle of conservation of energy and measure the components of work-energy theorem by Lesson 5.4 Power Essential Question: How do you calculate power? What is power? The rate at which work is done The rate of energy transfer by any method Technical Definition Power is a quantity that measures the rate at which work is done or energy is transformed More Power!!!!!. What does he mean?. Work. Work is the product of . force and distance. For a force to do work on an object, the object must . move in the same direction of the force. Any force that .
